[0048] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0049] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this application pertains.

[0050] The Basic Input / Output System (BIOS) is the first program to run during computer startup, responsible for initializing hardware and loading the operating system. During production and repair, it is necessary to frequently enter the BIOS interface for settings and testing to diagnose and maintain the computer.

[0051] Currently, to enter the BIOS interface, users need to manually press the power button on the computer case and then quickly press a specific hotkey (such as F1, F2, or Del) during the boot process. This process requires users to monitor the boot status in real time, and is prone to failure due to improper operation.

[0052] The BIOS acts as a bridge between computer hardware and the operating system, ensuring that the computer can boot and run the operating system normally. For example, during computer manufacturing, it is necessary to enter the BIOS to confirm that all hardware components are correctly recognized and initialized; during user operation, when problems are found with the computer, the BIOS interface can be accessed to diagnose the root cause of the problem.

[0053] After research, the inventors discovered that because computers boot up very quickly, users need to manually press the correct hotkey within a short time window, which increases the risk of misoperation. Furthermore, different brands and models of computers may use different hotkeys to enter the BIOS interface, which further increases the difficulty for users to operate correctly.

[0054] Based on the above considerations, in order to accurately enter the BIOS interface, the inventors, through in-depth research, designed a control device. When the control unit 1 controls the power management unit 2 to turn on the device under test, the keyboard and mouse emulator can enable the device under test to enter the basic input / output system based on the signal issued by the control unit 1.

[0055] The device under test in this application can be a computer, server, embedded system, etc.

[0056] Example 1

[0057] like Figure 1 and Figure 2 As shown, Embodiment 1 of this application provides a control device, including:

[0058] Control Unit 1;

[0059] Power management unit 2 is connected to the control unit 1 and the device under test via signals, respectively;

[0060] A keyboard and mouse simulator is connected to the control unit 1 and the device under test, respectively.

[0061] When the control unit 1 controls the power management unit 2 to turn on the device under test, the keyboard and mouse simulator can enable the device under test to enter the basic input / output system based on the signal issued by the control unit 1.

[0062] Specifically, the control unit 1 is the central processing unit of the entire control device. It is responsible for coordinating and controlling the operation of other components, and managing the power management unit 2 and the keyboard and mouse simulator by sending commands. The control unit 1 can be a microcontroller unit; or, the control unit 1 can be an embedded computing platform based on Raspberry Pi to reduce production costs while ensuring computing power and flexibility.

[0063] A Raspberry Pi-based embedded computing platform can include a Raspberry Pi development board and a Raspberry Pi touchscreen display. The development board is the core technology module, responsible for executing the main computing tasks and control logic. The touchscreen display shows system status and the user interface; its touch functionality enables user interaction with the control unit 1, simplifying the operation process. To ensure stable data transmission and power supply, the development board can be connected to the touchscreen display via a cable. To enable connectivity with more external devices, the Raspberry Pi-based embedded computing platform can also include a GPIO (General Purpose Input / Output) expansion board. The GPIO expansion board can connect to the development board via a two-wire interface or a serial peripheral interface. The GPIO expansion board provides additional pins and interfaces, allowing the control unit 1 to connect to more peripheral devices, such as a 231 relay or a keyboard and mouse emulator. The touchscreen display can be connected to the development board via the GPIO expansion board.

[0064] Power Management Unit 2 is responsible for receiving control commands from Control Unit 1 and turning the power supply of the device under test (DUT) on or off according to the control commands. Power Management Unit 2 can be wired to Control Unit 1, for example, via a cable or connector, to provide a stable and reliable communication path; or, Power Management Unit 2 can be wirelessly connected to Control Unit 1, for example, via a Bluetooth module or wireless network module, to improve flexibility. When Control Unit 1 uses a Raspberry Pi-based embedded computing platform, Power Management Unit 2 can be wired or wirelessly connected to the development board; or, Power Management Unit 2 can be wired to the GPIO expansion board. The specific connection method for Power Management Unit 2 to the DUT can be found in the connection method between Power Management Unit 2 and Control Unit 1.

[0065] The power management unit 2 can simulate the action of manually pressing a power button through a physical mechanism, for example, by directly pressing the power button on the device under test through a robotic arm; or, the power management unit 2 can control the power status of the device under test by sending electronic signals.

[0066] The keyboard and mouse emulator is used to simulate keyboard and mouse operations, enabling input control of the device under test. The emulator can be wired to the control unit 1 via a cable or connector to provide a stable and reliable communication path; alternatively, it can be wirelessly connected to the control unit 1 via Bluetooth or a wireless network module to enhance flexibility. The specific connection method for the emulator to the device under test can be found in the connection instructions for the keyboard and mouse emulator and control unit 1.

[0067] The keyboard and mouse simulator can use pre-configured human-machine interface (HMI) modules to reduce production costs; alternatively, when the control unit 1 uses a Raspberry Pi-based embedded computing platform, the simulator can include a core chip and an interface converter chip to provide greater flexibility and customization. The interface converter chip connects to the development board, providing serial communication capabilities; it also connects to the core chip via a serial communication interface to ensure stable signal transmission; the core chip connects to the device under test (DUT), simulating keyboard and mouse input / output information based on signals received from the development board. The core chip can be a CH9329 or an ATmega32U4, etc. The interface converter chip can be a CH340 or an FT232R, etc.

[0068] The number of power management units 2 can be multiple, and each power management unit 2 can be connected to a control unit 1. The number of keyboard and mouse emulators can be the same as the number of power management units 2, and each keyboard and mouse emulator can be connected to a control unit 1. Each power management unit 2 corresponds to one keyboard and mouse emulator, serving a single device under test (DUT). With this configuration, a single control unit 1 can remotely coordinate and control multiple power management units 2 and their corresponding keyboard and mouse emulators, enabling batches of DUTs to enter the BIOS interface, significantly improving work efficiency. The control device provided in Embodiment 1 of this application utilizes the control unit 1 to coordinate and control the operation of each component, simplifying the operation process. The power management units 2 can accurately power on the DUT according to the instructions of the control unit 1, ensuring that the device can start promptly when needed. The keyboard and mouse emulators can simulate the user's keyboard and mouse operations according to the signals issued by the control unit 1 after the DUT is powered on, enabling the DUT to enter the BIOS interface. This process requires no manual intervention, achieving automated operation of the BIOS interface, reducing the risk of errors caused by improper human operation, and ensuring accurate and rapid entry into the BIOS interface.

[0069] like Figure 1 and Figure 2 As shown, in some embodiments, the power management unit 2 may include:

[0070] Clamping assembly 21 is used to clamp the device under test;

[0071] A linear actuator 22 is disposed on the clamping assembly 21, and the linear actuator 22 is signal-connected to the control unit 1; the actuating end of the linear actuator 22 is used to face the power switch of the device under test to trigger the power switch.

[0072] Specifically, the clamping assembly 21 is used to securely clamp the device under test, ensuring that the linear actuator 22 will not move or fall off during operation, thus guaranteeing the stability and safety of the measurement. The clamping assembly 21 can be a clamp.

[0073] The linear actuator 22 physically contacts the power switch through its actuating end and applies a certain pressure to the power switch, thereby triggering the power switch. The installation position of the linear actuator 22 can be specifically designed according to the location of the power switch of the device under test, so that after the clamping assembly 21 clamps the device under test, the actuating end of the linear actuator 22 is directly opposite the power switch to achieve effective subsequent triggering. The linear actuator 22 can be connected to the clamping assembly 21 using bolts, screws, or other fasteners to ensure stability and accuracy. The linear actuator 22 can have a certain stroke length to ensure that the actuating end can fully press the power switch. The linear actuator 22 can be made of a linear motor, hydraulic cylinder, or pneumatic cylinder, etc.

[0074] The power management unit 2 may include a flexible component that can be connected to the actuation end of the linear actuator 22. The flexible component is used to contact the power switch to increase the contact area with the power switch while ensuring the integrity of the power switch.

[0075] Before testing, manually attach the clamping assembly 21 to the device under test, and adjust the clamping position of the clamping assembly 21 so that the actuating end of the linear actuator 22 is directly opposite the power switch.

[0076] The clamping assembly 21 ensures the stability of the device under test during operation, guaranteeing operational safety. The linear actuator 22 can precisely trigger the power switch according to the instructions of the control unit 1, ensuring consistency and accuracy in each operation. The entire operation process is simple and efficient.

[0077] like Figure 2 As shown, in some embodiments, the clamping assembly 21 may include:

[0078] Mounting component 211 is connected to the linear actuator 22;

[0079] Two clamping arms 212 are spaced apart on the mounting member 211; the distance between the two clamping arms 212 can be adjusted to jointly clamp the device under test.

[0080] Specifically, the mounting member 211 is used to ensure the stability and accuracy of the entire clamping assembly 21. The mounting member 211 may be strip-shaped, with its length direction being a first direction A. Two clamping arms 212 may be connected to the mounting member 211 at intervals along the first direction A. A linear actuator 22 may be located between the two clamping arms 212, and the linear actuator 22 may be connected to the mounting member 211 by bolts or other fasteners.

[0081] The distance between the two clamping arms 212 is adjustable. For example, one clamping arm 212 can be connected to the mounting member 211 by bolts or snap-fit. The mounting member 211 can be configured with a first slide rail extending along a first direction A. The other clamping arm 212 can be slidably connected to the mounting member 211 via the first slide rail. In this case, the clamping assembly 21 can also include a first abutting screw, which can be slidably connected to the first slide rail along the first direction A. By unscrewing the first abutting screw, the other clamping arm 212 is allowed to slide along the first slide rail; by screwing in the first abutting screw, the first abutting screw can abut against the clamping arm 212 to restrict its sliding, thereby maintaining the distance between the two clamping arms 212. Alternatively,

[0082] Both clamping arms 212 can be slidably connected to the mounting piece 211 along the first direction A via the first slide rail. At this time, there are two first abutting screws, each corresponding to one clamping arm 212. The positions of the two clamping arms 212 are controlled by screwing in and out of the first abutting screws, thus adjusting the spacing; or...

[0083] The clamping assembly 21 may include a screw, the length of which is in the same direction as the first direction A. The screw is rotatably connected to the mounting member 211 about the first direction A. The screw may be configured with two threaded segments with opposite thread directions. Each of the two clamping arms 212 is threadedly connected to one of the threaded segments. By rotating the screw, the two clamping arms 212 can be moved closer or further apart, thereby adjusting the spacing; or...

[0084] At least three slots can be configured on the mounting piece 211 along the first direction A, and the two clamping arms 212 can be adjusted by engaging with the slots at different positions.

[0085] The above are just a few possible adjustment methods. Any mechanism that can achieve spacing adjustment is applicable to this clamping assembly 21.

[0086] The clamping assembly 21 may also have two fixing members 24, each of which is connected to a clamping arm 212. The fixing members 24 are used to enhance the stability of the connection of the clamping assembly 21. The fixing members 24 can be suction cups, which are used to adsorb the device under test; or, the fixing members 24 can be magnetic components, which can magnetically attract the device under test.

[0087] By setting two adjustable clamping arms 212, the clamping assembly 21 can adapt to devices of various sizes, improving the versatility and flexibility of the control device. Furthermore, by adjusting the spacing of the clamping arms 212, the clamping force can be evenly distributed, which can prevent the clamping assembly 21 from sliding or falling off, and reduce the risk of damage to the surface of the device under test, thereby improving the safety and reliability of operation.

[0088] like Figure 2 As shown, in some embodiments, the mounting member 211 may have multiple mounting positions (not shown in the figure), and the linear actuator 22 can be aligned with the power switch in different positions by connecting to the mounting positions in different locations.

[0089] Specifically, the mounting component 211 may have multiple mounting holes arranged along the first direction A. The linear actuator 22 is detachably connected to the mounting component 211 through the mounting holes, with each mounting hole forming a mounting position. The number of mounting holes can be two, three, four, or even more. Alternatively,

[0090] Mounting member 211 may have a second slide extending along a first direction A. Linear actuator 22 can be slidably connected to mounting member 211 along the first direction A via the second slide, and the second slide forms multiple mounting positions. At this time, clamping assembly 21 also includes a second abutting screw, which can be slidably connected to the second slide along the first direction A. By unscrewing the second abutting screw, linear actuator 22 is allowed to slide along the second slide; by screwing in the second abutting screw, the second abutting screw can abut against linear actuator 22 to restrict its sliding, so as to maintain the stability of linear actuator 22 and ensure the accuracy of control.

[0091] Multiple mounting positions allow the linear actuator 22 to adapt to power switches in different locations, thereby supporting a variety of types of devices under test and improving the versatility and applicability of the control device.

[0092] like Figure 2 and Figure 3 As shown, in some embodiments, the linear actuator 22 may include:

[0093] Drive component 221 is disposed on the clamping assembly 21;

[0094] A first connector 222, the first end of which is connected to the driving end of the driving member 221;

[0095] The second connector 223 is rotatably connected to the second end of the first connector 222.

[0096] Push rod 224, the first end of which is rotatably connected to the second end of the second connector 223, and the push rod 224 is slidably connected to the drive member 221.

[0097] Specifically, the drive component 221 is the power source for the linear actuator 22, responsible for converting electrical energy into mechanical energy. The drive component 221 can be connected to the mounting component 211 by bolts or other fasteners to ensure its stability.

[0098] The first connector 222 and the second connector 223 are used to transmit the power generated by the drive member 221 and convert it into linear motion of the push rod 224. The first end of the first connector 222 can be connected to the drive end of the drive member 221 via a key or pin, and the second end of the first connector 222 can be hinged to the first end of the second connector 223 or connected via a rotary joint to achieve relative rotational motion. The second end of the second connector 223 can be hinged to the first end of the push rod 224 or connected via a rotary joint to achieve relative rotational motion. The first connector 222 can be a crank or a connecting rod, and the second connector 223 can be a crank or a connecting rod, etc.

[0099] The push rod 224 can move linearly along the desired path. The second end of the push rod 224 is positioned directly opposite the power switch. The drive unit 221 can be configured with a guide structure 226, which can be a guide seat or a guide groove. The middle part of the push rod 224 is slidably connected to the drive unit 221 through the guide structure 226, ensuring that the push rod 224 always maintains the correct path during movement, thereby achieving precise triggering of the power switch.

[0100] The drive component 221 drives the push rod 224 to make linear motion through the first connector 222 and the second connector 223. This multi-component design can disperse the point of force application, reduce the stress on a single component, extend the service life of the linear actuator 22, and improve its reliability.

[0101] like Figure 2 and Figure 3 As shown, in some embodiments, the power management unit 2 may further include:

[0102] The expansion contact 225 is connected to the actuating end of the linear actuator 22;

[0103] The contact extender 225 has a contact surface whose shape is adapted to the power switch for stable contact with the power switch.

[0104] Specifically, the contact extender 225 adapts to power switches of different shapes through its contact surface to provide stable and reliable contact and ensure uniform pressure distribution, avoiding damage caused by excessive local pressure. For example, when the surface of the power switch is a curved surface that is concave in the center, the contact surface can also be a curved surface that is concave in the center, so that the contact surface can completely fit with the surface of the power switch and ensure uniform pressure distribution; when the surface of the power switch is flat, the contact surface can also be flat, so that the contact surface can completely fit with the surface of the power switch and ensure stable and reliable contact.

[0105] like Figure 1 and Figure 2 As shown, in some embodiments, the power management unit 2 may include:

[0106] Power control lines (not shown in the figure) are used to electrically connect to the pins of the power switch of the control unit 1 and the device under test, respectively.

[0107] Electronic switch 23 is used to electrically connect to the control unit 1 and the device under test, respectively. The control unit 1 can control the electronic switch 23 to turn on the device under test.

[0108] Specifically, the power control lines include two lines. The first end of the first power control line is electrically connected to the control unit 1 to transmit control signals. The first end of the second power control line is electrically connected to the pin of the power switch. The second ends of both power control lines are electrically connected to the electronic switch 23 to receive control signals from the control unit 1 and control the power supply to the device under test. The control unit 1 can send control signals to the electronic switch 23 via the power control lines to turn the power supply to the device under test on and off. The electronic switch 23 can be electrically connected to an external power source; alternatively, the control unit 1 can be electrically connected to an external power source. The power control lines can be cables or ribbon cables, etc. The electronic switch 23 can be a relay 231 or a bidirectional thyristor, etc.

[0109] The electronic switch 23 can be at least one of a relay 231 and a switch changer 232. When the electronic switch 23 includes both a relay 231 and a switch changer 232, the relay 231 can be used to manage high-voltage and high-current main power supplies. For example, if the test equipment experiences a severe software crash or hardware failure, causing it to be unable to respond normally to the power button operation, the relay 231 can be used to completely cut off the power. The switch changer 232 can be used to simulate the operation of a low-voltage power button. For example, during a normal test procedure, the system can use the switch changer 232 to simulate pressing the power button to start or stop the device under test without cutting off the main power supply, thereby maintaining the continuity of the internal state of the device and the security of the data.

[0110] The device under test is turned on by controlling the electronic switch 23, which reduces the need for manual operation, improves testing efficiency, and is suitable for frequent BIOS interface access during the production process.

[0111] The power management unit 2 can be configured as either an electronic switch 23 or a mechanical control, or a combination of both.

[0112] like Figure 1 and Figure 4 As shown, in some embodiments, it may further include:

[0113] The video acquisition unit 3 is used to connect to the control unit 1 via a signal, and the acquisition end of the video acquisition unit 3 is used to face the display of the device under test.

[0114] Specifically, the video acquisition unit 3 is used to capture the image displayed on the device under test and transmit the image data to the control unit 1. The video acquisition unit 3 can be wired to the control unit 1, for example, via a cable or connector, to provide a stable and reliable communication path; alternatively, the video acquisition unit 3 can be wirelessly connected to the control unit 1, for example, via a Bluetooth module or a wireless network module, to improve flexibility. The video acquisition unit 3 can be a camera or an embedded vision system, etc.

[0115] Control unit 1 can send commands to power management unit 2 and video acquisition unit 3 respectively. Power management unit 2 can accurately turn on the device under test according to the command of control unit 1. Video acquisition unit 3 captures the screen of the device under test according to the command of control unit 1 and transmits the screen to control unit 1 in real time. Control unit 1 confirms that the device under test has started successfully by capturing the screen of the device under test by video acquisition unit 3. Then, control unit 1 sends a command to make the keyboard and mouse emulator simulate the user's keyboard and mouse operations, so that the device under test enters the BIOS interface. Control unit 1 confirms that the device under test has successfully entered the BIOS interface by capturing the screen of the device under test by video acquisition unit 3.

[0116] After entering the BIOS interface, the BIOS can be configured through a keyboard and mouse emulator. During the BIOS configuration phase, manual settings can be selected. For example, the user can perform clicks or swipes through the BIOS interface, which are then sent to the device under test via the keyboard and mouse emulator to select the corresponding function. Alternatively, control logic can be preset in the control unit 1. The control unit 1 can identify the current BIOS interface status and available options based on the screen content fed back by the video acquisition unit 3. The control unit 1 determines the next operation to be performed according to the preset control logic and automatically drives the keyboard and mouse emulator to complete the corresponding function adjustment (such as adjusting the boot order, changing the system time, etc.) or testing.

[0117] like Figure 1 and Figure 4 As shown, in some embodiments, it may further include:

[0118] The housing 4 has an accommodating space and a collection hole 43; the collection hole 43 is connected to the accommodating space;

[0119] Both the control unit 1 and the video acquisition unit 3 are located within the accommodating space and connected to the housing 4; the acquisition end of the video acquisition unit 3 is opposite to the acquisition hole 43.

[0120] Specifically, housing 4 provides physical protection for control unit 1 and video acquisition unit 3. The controller can be connected to the inner wall of housing 4 via bolts or other fasteners; the video acquisition unit 3 can also be connected to the inner wall of housing 4 via bolts or other fasteners. When power management unit 2 includes a power control line and electronic switch 23, electronic switch 23 can be located within the accommodating space and can be connected to the inner wall of housing 4 via bolts or other fasteners.

[0121] The housing 4 may include multiple panels 41 and a fixing bracket 42. The multiple panels 41 can be connected by bolts or welding to form the housing 4. The fixing bracket 42 is located within the accommodating space and can be in the form of a gantry structure. Each component can be fixed to the housing 4 by the fixing bracket 42 and bolts. The fixing bracket 42 is used to restrict the movement of each component and ensure stability. The housing 4 may have multiple wiring holes for power control lines and other wiring to pass through.

[0122] Example 2

[0123] Embodiment 2 of this application provides a testing system, including:

[0124] Main control equipment;

[0125] like Figure 1 and Figure 2 As shown, the control device includes:

[0126] Control unit 1, which is signal-connected to the main control device;

[0127] Power management unit 2 is connected to the control unit 1 and the device under test via signals, respectively;

[0128] A keyboard and mouse simulator is connected to the control unit 1 and the device under test, respectively.

[0129] When the control unit 1 receives the target signal sent by the main control device, it controls the power management unit 2 to turn on the device under test and controls the keyboard and mouse simulator to control the device under test to enter the basic input / output system.

[0130] Specifically, the main control device can be wired to the control unit 1, for example, via a cable or connector to provide a stable and reliable communication path; or, the main control device can be wirelessly connected to the control unit 1, for example, via a Bluetooth module or a wireless network module to improve flexibility. The main control device can be a computer or an industrial controller, etc.

[0131] When the control device includes multiple power management units 2 and multiple keyboard and mouse emulators, a single master control device can be connected to a single control unit 1 of the control device via a signal connection. This enables the single master control device to remotely coordinate and control multiple power management units 2 and their corresponding keyboard and mouse emulators, allowing a batch of devices under test to enter the BIOS interface and greatly improving work efficiency.

[0132] The control device can include multiple devices, and the control unit 1 of each control device is connected to the main control device via signal connection. This enables a single main control device to remotely coordinate and control multiple control devices, allowing a batch of devices under test to enter the BIOS interface and greatly improving work efficiency.

[0133] The two methods described above for the main control device to batch control the devices under test to enter the BIOS can be selected individually or combined. The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
